FIELD OF THE INVENTION

This invention is in the field of medicinal chemistry and relates to compounds, and pharmaceutical compositions thereof, that inhibit bacterial gyrase and Topo IV. The compounds are useful as inhibitors of bacterial gyrase and Topo IV activity. The present invention also relates to methods of using the compounds of this invention for treating resistant bacterial infections in patients. The present invention also relates to treating resistant bacterial infections in patients using compounds of the present invention in combination with one or more additional antibacterial agents and/or one or more additional therapeutic agents that increase the susceptibility of bacterial organisms to antibiotics.

BACKGROUND OF THE INVENTION

Bacterial resistance to antibiotics has long been recognized, and it is today considered to be a serious worldwide health problem. As a result of resistance, some bacterial infections are either difficult to treat with antibiotics or even untreatable. This problem has become especially serious with the recent development of multiple drug resistance in certain strains of bacteria, such as Streptococcus pneumoniae (SP), Mycobacterium tuberculosis, and Enterococcus. The appearance of vancomycin resistant enterococcus was particularly alarming because vancomycin was formerly the only effective antibiotic for treating this infection, and had been considered for many infections to be the drug of “last resort”. While many other drug-resistant bacteria do not cause life-threatening disease, such as enterococci, there is the fear that the genes which induce resistance might spread to more deadly organisms such as Staphylococcus aureus, where methicillin resistance is already prevalent (De Clerq, et al., Current Opinion in Anti-infective Investigational Drugs, 1999, 1, 1; Levy, “The Challenge of Antibiotic Resistance”, Scientific American, March, 1998).

Another concern is how quickly antibiotic resistance can spread. For example, until the 1960's SP was universally sensitive to penicillin, and in 1987 only 0.02% of the SP strains in the U.S. were resistant. However, by 1995 it was reported that SP resistance to penicillin was about seven percent and as high as 30% in some parts of the U.S. (Lewis, FDA Consumer magazine (September, 1995); Gershman in The Medical Reporter, 1997).

Hospitals, in particular, serve as centers for the formation and transmission of drug-resistant organisms. Infections occurring in hospitals, known as nosocomial infections, are becoming an increasingly serious problem. Of the two million Americans infected in hospitals each year, more than half of these infections resist at least one antibiotic. The Center for Disease Control reported that in 1992, over 13,000 hospital patients died of bacterial infections that were resistant to antibiotic treatment (Lewis, “The Rise of Antibiotic-Resistant Infections”, FDA Consumer magazine, September, 1995).

As a result of the need to combat drug-resistant bacteria and the increasing failure of the available drugs, there has been a resurgent interest in discovering new antibiotics. One attractive strategy for developing new antibiotics is to inhibit DNA gyrase, a bacterial enzyme necessary for DNA replication, and therefore, necessary for bacterial cell growth and division. Gyrase activity is also associated with events in DNA transcription, repair and recombination.

Gyrase is one of the topoisomerases, a group of enzymes which catalyze the interconversion of topological isomers of DNA (see generally, Kornberg and Baker, DNA Replication, 2d Ed., Chapter 12, 1992, W.H. Freeman and Co.; Drlica, Molecular Microbiology, 1992, 6, 425; Drlica and Zhao, Microbiology and Molecular Biology Reviews, 1997, 61, 377). Gyrase itself controls DNA supercoiling and relieves topological stress that occurs when the DNA strands of a parental duplex are untwisted during the replication process. Gyrase also catalyzes the conversion of relaxed, closed circular duplex DNA to a negatively superhelical form which is more favorable for recombination. The mechanism of the supercoiling reaction involves the wrapping of gyrase around a region of the DNA, double strand breaking in that region, passing a second region of the DNA through the break, and rejoining the broken strands. Such a cleavage mechanism is characteristic of a type II topoisomerase. The supercoiling reaction is driven by the binding of ATP to gyrase. The ATP is then hydrolyzed during the reaction. This ATP binding and subsequent hydrolysis cause conformational changes in the DNA-bound gyrase that are necessary for its activity. It has also been found that the level of DNA supercoiling (or relaxation) is dependent on the ATP/ADP ratio. In the absence of ATP, gyrase is only capable of relaxing supercoiled DNA.

Bacterial DNA gyrase is a 400 kilodalton protein tetramer consisting of two A (GyrA) and two B subunits (GyrB). Binding and cleavage of the DNA is associated with GyrA, whereas ATP is bound and hydrolyzed by the GyrB protein. GyrB consists of an amino-terminal domain which has the ATPase activity, and a carboxy-terminal domain which interacts with GyrA and DNA. By contrast, eukaryotic type II topoisomerases are homodimers that can relax negative and positive supercoils, but cannot introduce negative supercoils. Ideally, an antibiotic based on the inhibition of bacterial DNA gyrase would be selective for this enzyme and be relatively inactive against the eukaryotic type II topoisomerases.

The widely used quinolone antibiotics inhibit bacterial DNA gyrase. Examples of the quinolones include the early compounds such as nalidixic acid and oxolinic acid, as well as the later, more potent fluoroquinolones such as norfloxacin, ciprofloxacin, and trovafloxacin. These compounds bind to GyrA and stabilize the cleaved complex, thus inhibiting overall gyrase function, leading to cell death. However, drug resistance has also been recognized as a problem for this class of compounds (WHO Report, “Use of Quinolones in Food Animals and Potential Impact on Human Health”, 1998). With the quinolones, as with other classes of antibiotics, bacteria exposed to earlier compounds often quickly develop cross-resistance to more potent compounds in the same class.

There are fewer known inhibitors that bind to GyrB. Examples include the coumarins, novobiocin and coumermycin A1, cyclothialidine, cinodine, and clerocidin. The coumarins have been shown to bind to GyrB very tightly. For example, novobiocin makes a network of hydrogen bonds with the protein and several hydrophobic contacts. While novobiocin and ATP do appear to bind within the ATP binding site, there is minimal overlap in the bound orientation of the two compounds. The overlapping portions are the sugar unit of novobiocin and the ATP adenine (Maxwell, Trends in Microbiology, 1997, 5, 102).

For coumarin-resistant bacteria, the most prevalent point mutation is at a surface arginine residue that binds to the carbonyl of the coumarin ring (Arg136 in E. coli GyrB). While enzymes with this mutation show lower supercoiling and ATPase activity, they are also less sensitive to inhibition by coumarin drugs (Maxwell, Mol. Microbiol., 1993, 9, 681).

Despite being potent inhibitors of gyrase supercoiling, the coumarins have not been widely used as antibiotics. They are generally not suitable due to their low permeability in bacteria, eukaryotic toxicity, and poor water solubility (Maxwell, Trends in Microbiology, 1997, 5, 102). It would be desirable to have a new, effective GyrB inhibitor that overcomes these drawbacks. Such an inhibitor would be an attractive antibiotic candidate, without a history of resistance problems that plague other classes of antibiotics.

Replication fork movement along circular DNA can generate topological changes both ahead of the replication complex as well as behind in the already replicated regions (Champoux, J. J., Annu. Rev. Biochem., 2001, 70, 369-413). While DNA gyrase can introduce negative supercoils to compensate for the topological stresses ahead of the replication fork, some overwinding can diffuse back into the already replicated region of DNA resulting in precatenanes. If not removed, the presence of the precatenanes can result in interlinked (catenated) daughter molecules at the end of replication. TopoIV is responsible for separating the catenated daughter plasmids as well as removal of precatenanes formed during replication ultimately allowing for segragation of the daughter molecules into daughter cells. Topo IV is composed of two ParC and 2 parE subunits as a C₂E₂ tetramer (where the C and E monomers are homologous to the A and B monomers of gyrase, respectively) that requires ATP hydrolysis (at the N-terminus of the E subunit) to reset the enzyme to re-enter the catalytic cycle. Topo IV is highly conserved among bacteria and is essential for bacterial replication (Drlica and Zhao, Microbiol. Mol. Biol. Rev., 1997, 61, 377).

While little attention has been paid to inhibitors that target ParE of TopoIV, the action of the newer quinolones on the ParC region has been widely studied (Hooper, D. C., Clin. Infect. Dis., 2000, 31(Suppl 2): S24-28). It has been demonstrated that moxifloxacin and gatifloxacin have more balanced activities against Gyrase and TopoIV resulting in expanded Gram positive coverage as well as lower levels of resistance caused primary-target mutation. In those cases, susceptibility is limited by the sensitivity of the second target to the antibacterial agent. Thus, agents that can effectively inhibit multiple essential targets can result in an expanded spectrum of potencies, improved antibacterial potencies, improved potency against single target mutants, and/or lower spontaneous rates of resistance.

As bacterial resistance to antibiotics has become an important public health problem, there is a continuing need to develop newer and more potent antibiotics. More particularly, there is a need for antibiotics that represent a new class of compounds not previously used to treat bacterial infection. Such compounds would be particularly useful in treating nosocomial infections in hospitals where the formation and transmission of resistant bacteria are becoming increasingly prevalent.

The term “hydrogen bond acceptor”, as used herein, means an atom capable of accepting a hydrogen bond. A typical hydrogen bond acceptor is a sulfur, oxygen, or nitrogen atom, especially a nitrogen that is sp²-hybridized, an ether oxygen, or a thioether sulfur. A preferred hydrogen bond acceptor is a nitrogen that is sp²-hybridized.

A combination of substituents or variables is permissible only if such a combination results in a stable or chemically feasible compound. A stable compound or chemically feasible compound is one that is not substantially altered when kept at a temperature of 40° C. or less, in the absence of moisture or other chemically reactive conditions, for at least a week.

It will be apparent to one skilled in the art that certain compounds of this invention may exist in tautomeric forms, all such tautomeric forms of the compounds being within the scope of the invention.

The compounds of this invention may be prepared in general by methods known to those skilled in the art for analogous compounds, as illustrated by the general Schemes I, II, III, IV, and V shown below and the Examples set forth infra.

Scheme I above shows a general method for preparing N′-alkyl-N-cyanoureas 3 useful in the preparation of the compounds of the present invention wherein Z is NH. At step (a), cyanamide 2 was treated with an alkyl isocyanate in aqueous sodium hydroxide to afford, after acidification, compound 3. One of skill in the art would recognize that a variety of alkyl isocyanates would be amenable to the reaction conditions of Scheme I to form a variety of N′-alkyl-N-cyanoureas.

Scheme II above shows a general method for preparing the benzimidazole compounds of the present invention wherein Z is NH or O. The bromo-aniline 4 was treated with sodium perborate and acetic acid to form the difluoro-nitro compound 5. Compound 5 was treated with Ring A in the presence of sodium hydride to afford the bi-aryl compound 6. The remaining fluoro group of compound 6 was displaced with ammonia to form the amino compound 7. The 2-nitro-5-bromoaniline 7 was then coupled to an aryl boronic acid, at step (d), in the presence of palladium to form the tri-aryl compound 8. The nitro group of compound 8 was reduced to form a diamino compound which was either treated with an N′-alkyl-N-cyanourea 3 or with an N,N-dialkylureamido-2-methyl-2-thiopseudourea 3a to form a benzimidazole compound of formula I wherein Z is NH 9.

Alternatively, intermediate 8 may be used to form compounds of formula I wherein Z is O. Compound 10 was formed by treating 8, after reduction to the diamino compound, with 2-methyl-2-thiopseudourea and R²-chloroformate according to the method described by L. I. Kruse et al, J. Med. Chem. 1989, 32, 409-417. One of ordinary skill in the art would recognize that the reactions depicted in Scheme II above are amenable to a variety of R¹ and Ring A groups of the present invention.

In an alternative method, intermediate 8 was treated with either N,N-diethlycarboxy-2-methyl-2-thiopseudourea or N,N-diethlyureamido-2-methyl-2-thiopseudourea to form compounds 10 and 9, respectively. The syntheses of both N,N-diethlycarboxy-2-methyl-2-thiopseudourea and N,N-diethlyureamido-2-methyl-2-thiopseudourea are described in the Examples set forth infra.

Scheme III above shows a general method for preparing compounds of formula II-a using methods substantially similar to those described by Kiyomori, A.; Marcoux, J.-F.; Buchwald, S. L., Tetrahedron Letters, vol. 40, (1999) 2657-2660. Compound 7 was treated with diboronic ester in the presence of Pd(dppf)/potassium acetate in DMSO at 80° C. to afford intermediate 11. Compound 11 was treated with 4-C(O)N(R′)₂-imidazole in the presence of copper acetate to form the 4-C(O)N(R′)₂-imidazol-1-yl compound 12. Compounds of formula II-a were prepared from compound 12 as described in Scheme II, steps (e), (f), and (g).

Although 4-C(O)N(R′)₂-imidazole was used to exemplify, one of ordinary skill in the art would recognize that a variety of R¹ groups are amenable to the displacement reaction at step (c) to form a variety of compounds of the present invention. Generally, the boronate intermediate 11 may be treated with a variety of R¹-halides or R¹-triflates, using methods well known to one of ordinary skill in the art, to form intermediate compounds 12′ as shown below. Using the methods recited herein and those known to one of ordinary skill in the art, compounds 12′ are useful for preparing compounds 9 and 10 of the present invention as depicted above at Scheme II.

Scheme IV above shows an alternate method for preparing compounds of formula II-a. Compound 13 was nitrated to form 14. Compound 14 was treated with ammonium hydroxide to form the amino compound 15. The bromo group of compound 15 was treated with the BrZn-Ring A reagent in the presence of Pd(PPh₃)₄ in THF to form compound 16. Compound 16 was treated with the 4-C(O)N(R′)₂-imidazole in the presence of sodium carbonate to form the 4-C(O)N(R′)₂-imidazol-1-yl compound 18. Compounds of formula II-a were then prepared from compound 18 as described in Scheme II, steps (e), (f), and (g).

Scheme V above shows a general method for preparing compounds of formula VII. Compound 19 (purchased commercially from CB Research) underwent Suzuki-type coupling with commercial reagents (purchased from Aldrich or Manchester Organics Limited) of type 20 to form intermediate 21. Compound 21 was brominated with bromine in acetic acid to form bromide 22, then nitrated with nitric acid in the presence of TFA and TFAA to form intermediate 23. Acidic hydrolysis of compound 23 provided aniline 24. The bromo group of compound 24 was converted into boronate ester 25 in the presence of Pd(PPh₃)₄ in buffered dioxane. Compound 25 underwent Suzuki-type coupling with intermediate 26 (prepared from the di-bromoheteroaryl ring D [commercially available from Aldrich, etc.] according to the procedure of Wang, X. et al., Tetrahedron Letters, vol. 41, (2000) 4335-4338) to prepare nitro aniline intermediate 27. Raney-nickel reduction of the nitro group in compound 27, followed by treatment with N,N-dialkylureamido-2-methyl-2-thiopseudourea 3a afforded benzimidazole compounds of formula VII. Compounds of formula VII wherein Ring C is:

and R⁶ is OMe are either prepared from compounds of formula 20, using scheme V, wherein formula 20 is 2-bromo-3-methoxypyridine (prepared according to methods known in the art from commercially available 2-bromo-3-hydroxy pyridine) or by the displacement of a 3-fluoro pyridine intermediate 24 (in scheme V) with methoxide in methanol.

Example 27 Gyrase ATPase Assay

The ATP hydrolysis activity of DNA gyrase was measured by coupling the production of ADP through pyruvate kinase/lactate dehydrogenase to the oxidation of NADH. This method has been described previously (Tamura and Gellert, 1990, J. Biol. Chem., 265, 21342).

ATPase assays are carried out at 30° C. in buffered solutions containing 100 mM TRIS pH 7.6, 1.5 mM MgCl₂, 150 mM KCl. The coupling system contains (final concentrations) 2.5 mM phosphoenol pyruvate, 200 μM nicotinamide adenine dinucleotide (NADH), 1 mM DTT, 30 ug/ml pyruvate kinase, and 10 ug/ml lactate dehydrogenase. 40 nanomolar enzyme (374 kDa Gyr A2B2 subunit from Staphylococcus aureus) and a DMSO solution of the inhibitor to a final concentration of 4% are added and the reaction mixture is allowed to incubate for 10 minutes at 30° C. The reaction is then started by the addition of ATP to a final concentration of 0.9 mM and the rate of NADH disappearance at 340 nanometers is measured over the course of 10 minutes. The K_(i) values are determined from rate versus concentration profiles.

Compounds of the present invention were found to inhibit gyrase. In certain embodiments, compounds of the present invention inhibit gyrase with a K_(i) value of less than 50 nM in the above assay.

Example 28 Topo IV ATPase Assay

The conversion of ATP to ADP by Topo4 enzyme is coupled to the conversion of NADH to NAD+ and measured by the change in absorbance at 340 nm. Topo4 is incubated with inhibitor (4% DMSO final) in buffer for 10 minutes at 30° C. Reaction is initiated with ATP and rates are monitored continuously for 20 minutes at 30° C. on a Molecular Devices SpectraMAX plate reader. The inhibition constant, Ki, is determined from plots of rate vs. [Inhibitor] fit to the Morrison Equation for tight binding inhibitors.

S. aureus Topo4 Buffer:

100 mM Tris 7.5, 2 mM MgCl2, 200 mM K.Glutamate, 2.5 mM phosphoenol pyruvate, 0.2 mM NADH, 1 mM DTT, 4.25 μg/mL linearized DNA, 50 μg/mL BSA, 30 μg/mL pyruvate kinase, and 10 μg/mL lactate dehyrodgenase (LDH).

E. coli Topo4 Buffer:

100 mM Tris 7.5, 6 mM MgCl2, 20 mM KCl, 2.5 mM phosphoenol pyruvate, 0.2 mM NADH, 10 mM DTT, 5.25 μg/mL linearized DNA, 50 μg/mL BSA, 30 μg/mL pyruvate kinase, and 10 μg/mL lactate dehyrodgenase (LDH).

Compounds of the present invention were found to inhibit TopoIV. In certain embodiments, compounds of the present invention inhibit TopoIV with a K_(i) value of less than 50 nM in the above assay.

Example 29 Susceptibility Testing in Liquid Media

Compounds of this invention were also tested for antimicrobial activity by susceptibility testing in liquid media. Such assays were performed within the guidelines of the latest NCCLS document governing such practices: “M7-A5 Methods for dilution Antimicrobial Susceptibility Tests for Bacteria that Grow Aerobically; Approved Standard—Fifth Edition (2000)”. Other publications such as “Antibiotics in Laboratory Medicine” (Edited by V. Lorian, Publishers Williams and Wilkins, 1996) provide essential practical techniques in laboratory antibiotic testing. Essentially, several discrete bacterial colonies of Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis, Enterococcus faecium, E. coli, Haemophilus influenzae, Staphylococcus epidermidis, or Staphylococcus saprophyticus (3 to 7) from a freshly streaked plate were transferred to an appropriate rich broth medium such as MHB (Mueller Hinton broth), supplemented where appropriate for the more fastidious organisms. This was grown overnight to high density followed by a 1 or 2-thousand-fold dilution to give an inoculation density of between 5×10⁵ and 5×10⁶ CFU per mL. Alternatively, the freshly picked colonies can be incubated at 37° C. for about 4 to 8 hours until the culture equals or exceeds a turbidity of a 0.5 McFarland standard (approximately 1.5×10⁸ cells per mL) and diluted to give the same CFU per mL as above. In a more convenient method, the inoculum was prepared using a commercially available mechanical device (the BBL PROMPT System) that involves touching five colonies directly with a wand, containing crosshatch grooves at its bottom, followed by suspension of the bacteria in an appropriate volume of saline. Dilution to the appropriate inoculum cell density was made from this cell suspension. The broth used for testing consists of MHB supplemented with 50 mg per L of Ca²⁺ and 25 mg per L of Mg²⁺. In the case of Staphylococcus aureus, the relative serum binding was measured in assays containing 50% frozen human serum in cation-adjusted Mueller Hinton broth. Standard dilution panels of control antibiotics were made and stored as in the NCCLS standard M7-A5, the dilution range typically being in the 128 μg per mL to 0.015 μg per mL (by 2-fold serial dilution). The test compounds were dissolved and diluted fresh for experimentation on the same day; the same or similar ranges of concentration as above being used. The test compounds and controls were dispensed into a multiwell plate and test bacteria added such that the final inoculation was approximately 5×10⁴ CFU per well and the final volume was 100 μL. The plates were incubated at 35° C. overnight (16 to 20 hours) and checked by eye for turbidity or quantitated with a multiwell plate reader. The endpoint minimal inhibitory concentration (MIC) is the lowest concentration of drug at which the microorganism tested (Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis, Enterococcus faecium, E. coli, Haemophilus influenzae, Staphylococcus epidermidis, or Staphylococcus saprophyticus) does not grow under the test conditions. Such determinations were also compared to the appropriate tables contained in the above two publications to ensure that the range of antibacterial activity is within the acceptable range for this standardized assay.

Compounds of the present invention were found to have antimicrobial activity in the above-described Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis, Enterococcus faecium, E. coli, Haemophilus influenzae, Staphylococcus epidermidis, and Staphylococcus saprophyticus MIC assays.
